1 Claim.

tained, all as will hereinafter more fully appear- In the accompanyingdrawing:-

Fig. 1 is a sideelevation of brushing, rubbing and massaging appliance,embodying this invention.

Fig.2 is a detail transverse section on line 2-2, Fig. 3.

Fig. 3 is a detail longitudinal section on line 3-3, Fig.2.

. Like reference numerals indicate like parts in the diiferent views.

In the preferred form of the invention shown in Fig. 1, the handle orcarrying member 1 of the appliance, is similar in shape and size to thehandle member of the ordinary tooth brush now in general use, and inthis improvement is formed of a moldable substance, such as bakelite orlike cellulose derivative. While the brushing and massaging member 2 isin the form of an elongated approximately rectangular block of sponge orporous india rubber, with the attaching face of the block stiffened andrendered of a substan-- tially solid nature.

Such stiffening will usually be attained by an infiltration of theattaching face of the block 2 with a solution of india rubber or otherlike material adapted to become solid by subsequent vulcanization orother analogous treatment, and thus produce a thin and approximatelyrigid layer or portion 3 on the attaching side of the aforesaid brushingand massaging member or block 2.

The material part of this improvement involves an integral formation onthe aforesaid approximately rigid attaching layer or portion 3 of themember or block 2, of a plurality of headed projections 4, preferably ofa spheroid or like bulbous form and arranged in spaced relav tionlengthwise of the block 2 and produced during the formation of the same.

In the usual manufacture of this appliance, after the production ofthe-massaging block 2, its semi-rigid base 3 and headed projections 4 7Qin the manner above set forth, the handle or carrying member 1, composedof bakelite or analogous moldable material is molded in a suitable moldaround the headed projections 4 on the contacting face of the semi-rigidportion 2 of the massaging block 2 to couple the manufacture of theappliance in the ,preferred form as the same as shown in Fig. 1.

Having thus fully described my invention'what I claim as new, is:-

A dental brushing and massaging implement of the type herein described,comprising a brushing and massaging member of an approximatelyrectangular block shape, formed of ous india rubber and having itsattaching side stiffened into an integral semi-rigid layer. which inturn is formed with depending headed extensions, and a handle formed ofmoldable material and'molded around said headed extensions, the heads ofsaid extensions having a bulbous form.
